Cambridge communique, item 8

Message-Id: <5.1.0.14.2.20020909094915.0460dec0@127.0.0.1>
To: RDF interest group <www-rdf-interest@w3.org>

The Cambridge Communique [1] cropped up a couple of times in recent 
exchanges, and prompted me to go re-read it.

I note item, 8 may be regarded as partially addressed by a recent RDFcore 
decision [2]:
[[
8. A new simplified XML transfer syntax for RDF and an API for accessing 
RDF data models should be produced. The RDF 1.0 transfer syntax remains a 
W3C Recommendation and applications are free to continue to use it. It is 
not a requirement that XML Schema be able to validate conformance to the 
full grammar of RDF 1.0 syntax (e.g. equivalence of elements and attributes).
]]

Now that the rdf:nodeID concept has been accepted, it would be fairly 
simple to profile a subset of RDF/XML that has a direct mapping to triple 
form; e.g.

   <rdf:Description {rdf:about='<subj>'|rdf:nodeID='<subjID>'} >
        { <property {rdf:resource='<obj>'|rdf:nodeID='<objID>'}/> |
          <property [rdf:parseType='Literal'] 
[xml:lang='...'] >literal</property>     }
   </rdf:Description>

(using {...|...} for alternatives, and [...] for optional elements)
